Speciation Analysis Of Uranium And Some Heavy Metals In Stream Sediments From Uranium Ore In Northern Guangdong, China

It aims to study the speciation analysis of uranium and some selected heavy metals in stream sediments of uranium ore. The results indicated that, the concentration of Cr, Mn, Tl, As, U and Pb was highly more than the background values, indicating the serious contamination. Cr, Tl and As is largely associated to the residual form. Mn, Pb and U are mainly focused on the bound to carbonates fractionation. However, it is not specifically for Cd and Co to mainly exist in which from.
